Question

Find the length of the bold arc. Round your answer to the nearest tenth.

Answer 1

62.83 m

Explanation:

Given that,

The radius of the circle, r = 15 cm

Major angle = 240°

We need to find the length of the bold arc. The formula used to find the arc length is given by :

`l=(\theta)/(360)* 2\pi r\\\\=(240)/(360)* 2\pi * 15\\\\=62.83\ m`

So, the length of the bold arc is equal to 62.83 m.
